Keyword descriptions

MEMORY
MEMORY
Set the maximum amount of memory allocated for a given test (in bytes)
This optional keyword expects a real. Default value: 2.5600000000000000E+08
COPY
copy 10
Tests the performance to copy two vectors.The results of these tests allow to determine the size of the cache of the CPU. This can be used to optimize the performance of theFFTSG library. Tests are repeated the given number of times.
This optional keyword expects an integer. Default value: 0
MATMUL
matmul 10
Tests the performance of different kinds of matrix matrix multiply kernels for the BLAS and F95 INTRINSIC matmul. Matrices up to 2**N+1 will be tested.
This optional keyword expects an integer. Default value: 0
FFT
fft 10
Tests the performance of all available FFT libraries for 3D FFTs Tests are repeated the given number of times.
This optional keyword expects an integer. Default value: 0
CLEBSCH_GORDON
clebsch_gordon 10
Tests the Clebsch-Gordon Coefficients. Tests are repeated the given number of times.
This optional keyword expects an integer. Default value: 0
variants: CLEBSCH
MPI
mpi 6
Tests mpi, quickly adapted benchmark code,will ONLY work on an even number of CPUs. comm is the relevant, initialized communicator. This test will produce messages of the size 8*10**requested_size, where requested_size is the value given to this keyword
This optional keyword expects an integer. Default value: 0
RANDOM_NUMBER_GENERATOR
rng 1000000
Tests the parallel random number generator (RNG)
This optional keyword expects an integer. Default value: 0
variants: RNG
EIGENSOLVER
eigensolver n m
Tests the eigensolver,ABS(n) is the matrix dimension: n > 0: the matrix will be filled WITH random numbers; n < 0: the matrix is READ from the formatted file named MATRIX; m > 0: eigenvalues will be calculated
This optional keyword expects precisely 2 integers. Default value: 0 0
